Core Viewpoint - The article presents a novel method for detecting ethephon residues in compound fertilizers using Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS/MS), addressing the lack of standardized methods for fertilizer matrices and providing a reliable technical foundation for regulatory monitoring and quality control [2][4][42]. Group 1: Method Development - A new UHPLC-MS/MS method was established to detect ethephon residues in compound fertilizers, optimizing key parameters based on SN/T 4522-2016 [4][7]. - The method replaced alkaline elution with an acidified extraction system (acetonitrile-0.1% formic acid), improving recovery rates from undetectable levels to 93.8%-104.5% [4][6]. - The method demonstrated excellent linearity (r=0.9993) within a range of 2-200 μg/L, with a quantitation limit of 0.005 mg/kg and relative standard deviation (RSD) of 1.3%-3.9% [4][29]. Group 2: Importance of Ethephon in Fertilizers - Ethephon is often added to fertilizers to enhance crop growth and development, but its presence raises concerns regarding potential residues in agricultural products [5][6]. - The complexity of compound fertilizers, which contain multiple nutrients and additives, necessitates effective monitoring of ethephon to ensure safety and compliance [5][7]. Group 3: Practical Application and Results - Actual sample testing revealed ethephon residues in commercial compound fertilizers, with detected levels of 0.008 mg/kg and 0.015 mg/kg in two batches [39][41]. - The study emphasizes the need for regulatory frameworks to monitor ethephon residues in fertilizers, highlighting the method's practical applicability for ensuring agricultural safety [42].
